MOLDING- DEVICE.

Specification of Letters Patent.

Patented July 20, 1909.

Application iled March 23, 1908. Serial No. 422,678.

To all 'whom it may concern:

Be it known that I, ALEXANDER M. THoMrsoN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Molding Devices, of which the following is a specification.

My invention relates to molding devices to provide convenient means whereby patterns may be applied to a mold board rapidly and accurately.

i y invention is illustrated in the accompanying drawings, wherein- Figure l is a plan view; FigQ, .a section on line 22 of Fig. 1; Fig. 3, a-section on the line 3-3 of' Fig. 1; Fig. 4, a plan view of a modified form of the device; Fig. 5, a similar plan view of a further modification; Fig. 6, a cross section on the line 6-6 of Fig. 5.

Like parts are indicated by the same letter in all the figures.

AA are end. bars oi' a frame, B B the side bars. The side bars have holes A1 A1 and the end bars slots B1 B1. v

C is the mold board mounted on transverse bars' C1 C1 and having the pins C2 C2 which project beyond its face and are adapted to be received into the holes A1. The frame serves as a support for the guide which consists of the two plates D D1 rigidly secured together to form a square or which may be one or both of them pivotallj,T mounted at their engaging edges D2, in that case being held in any position by the vertical set screw D3, as indicated in Fig. 4. These plates are mounted each on an arm D4, which projects over the frame and is slotted at D'L3 and adjustably secured in position by the bolt D, whose head D7 lies under the side bar oi' the frame Vand whose shank passesk through the slot B1 and whichis provided with a nut D8 whereby` the parts may be securely fixed in position.

J is a modification shown in Fig. l; plates D and D1 are set at an angle to the axis of' the arm and are rigid in position. In Fig. 4, the arm D4 is secured by the set screws E E which pass through the slot D in the arm and through a slide E1 adjustably secured on the side bar B by the thumb screw t2.

F is a rod or bar used as a substitute for the frame and serving also to support the guides. It is perforated at its end at F10 to receive the pins C2 on the mold board. Mounted on this bar so as to slide therealong,

is a slide F1 provided with a thumb nut F2 whereby it can be 'locked lin any position. Projecting from it is a perforated short bar F3 to which can be secured the guide F1 in any desired position by thumb screws F5. This guide is a thin plate marked and cut of a predetermined size to locate the position oi' a predetermined pattern.

G G are patterns of various kinds and H II the gates which connect them together in groups'. 1

In Fig. 1 the bars of the frame are shown as adj ustablyunited at the corners by means of set screws F9 and nuts F8 associated with the slot B1.

Yly apparatus as shown, embraces substantially the following: a mold board, a frame or bar thereon adapted to serve asa jig or support and guidesto locate the several patterns mounted on the jig or supports. rlhese guides are of various types or patterns and they may be mounted either on the frame or bar and so as to be adjustable therealong or with reference thereto and so asto be swung with the bar` or frame from one side of the board to theother.

It is to be understood that my drawings are to be taken as diagrammatic and consid erable alterations can bemade without de- )arting from the spirit of my invention. 7Vhat I have illustrated, sufficiently shows a working device or apparatus, but in its commercial form it might assume a very different character. I have shown modifications, thus indicating equivalent parts which may be substituted one for another under certain conditions.

The use and operation of my invention are as follows: A mold board of the proper size and shape and provided with means ywhereby the support or jig may be applied to it is placed in position. The means referred to preferably consist of pegs `or pins projecting from the face of the board and on its axial line. The frame is now applied to the board, its two holes engaging the two pins. The half of a given pattern will now be placed a proximately .in the position it ought to lave, and a guide will be adjusted so that it comes into proper guiding or spacing relation to such pattern. The guide is then secureljT fixed in position by the thumb screw. The pattern portion is now placed in position in contact with the guide and is then spiked to the board. rIhere may be any number of such adjustments and placings of pattern portions along either side of the board, or if there be but one typeof pattern, then Wh en the onehas 'been placed in position, the frame is picked up and. turned over so t-hat the guide comes on the other side of the axial line of the board. Here the .process is repeated, though of course, the position and adjustment of the guide will not be'changed. The frame can be turned over in both directions so that `with one guide four 'pattern portions may be set. VThus the board Will have lits face ycove-red With the pattern sections.

These Ypatterns can now be impressed in the usual manner in the flask portions and it ris obvious that when the parts are brought together the complete lask `will contain perfect molds.

Theadvantage ofthis apparatus is that the mold boards can be reused any number of times and the patterns can be placed 'upon them .inthe easiest, quickest and =most accurate manner. Skilled labor is fno longer nece essary.

It is obvious that the form of the guide and of the `pattern is 'of no importance. `In Fig. 4, I have shown a modified Eform of attachmentofhthe guide tothe side bar of the frame and a .pivotal arrangement of the portionsof the'guide. This is to adapt it for more'easy application to various ffo'rms ofipatte'rns. In Fig. 5, a further modification is shown, but the action is much the same. fHere the 'bar is raised after itsV attern Yposition is marked, and the .pattern tiien placed in -position fand spiked down. rThe |bar is then turned over and ythe oppositely positioned pattern piece is spiked to the board.

l claim: 1. A molding device comprising a base to receive the pattern sect1ons, a supportad'aptabljT fitted :thereon `a'nd guides on 'the support adapted to 'make floose contact with thepattern section.
